HUBBLE SPACE TELESCOPE
DAILY REPORT #1339
PERIOD COVERED: 0000Z (UTC) 03/02/95 - 0000Z (UTC) 03/03/95
Daily Status Report as of 062/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed GHRS/2 5094 (Composition of Gas in Individual Interstellar
Clouds: Cycle 4 Observations)
The High Resolution Spectrograph (Side 2) was used to look for
interstellar absorption lines in the star Eta Lup (aka, HD143118) to
determine the column densities of a number of atomic species in the cloud.
The observations were executed as scheduled. No other anomalies were noted.
1.2 Completed FOS/BL 5658 (White Dwarf Calibration)
The Faint Object Spectrograph (Blue Side) was used to make absolute
sensitivity calibrations of the detectors using standard white dwarf star
GD153. HSTAR #5140 reported that the FOS encountered a speed check failure at
061/0815Z. The status buffer error message indicated that the FOC was
overloaded. No other anomalies were noted.
1.3 Completed WF/PC-2 6140 (WF/PC-2 Cycle 4 Calibration: Ramp filters,
Internal Calibration)
The WF/PC-2 was used to make Earth calibration images as part of a
ramp filter calibration test. The observations were completed as planned and
no problems were reported.
1.4 Completed WF/PC-2 6142 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
Smaller Set Part II)
The WF/PC-2 was used to make Earth Flat calibration images for the
ultraviolet and narrow-band filters to correct for the telescope's
illumination pattern. The observations were executed as scheduled, and no
anomalies were noted.
1.5 Completed Two Sets of WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4
Medium, High Galactic Latitude)
The WF/PC-2 made a series of observations of high latitude objects as
part of a medium deep sky survey. The observations were taken in parallel
with other prime science observations. The observations were completed as
scheduled, and no anomalies were noted.
1.6 Completed FOS/BL 5460 (Constraints on Massive Star Evolution from
Carbon and Oxygen Abundance)
The FOS (Blue Side) was used to observe BR93 to obtain UV spectra of
several Wolf-Rayet stars in the LMC to determine the C/He and O/C ratios.
HSTAR #5143 reported that the FOS encountered a binary acquisition failure at
061/1451Z during observation #25. A routine status buffer error message was
received. No other anomalies were noted.
1.7 Completed FOS/BL 5444 (A UV Spectral Library of Metal- Poor Massive
Stars)
The FOS (Blue Side) was used for a snapshot program to obtain
ultraviolet spectra of NS172-66 a metal-poor star in the LMC. It will be
useful for stellar atmosphere and stellar evolution studies. The observations
completed without incident.
1.8 Completed FOC/96 5409 (Direct UV and Spectral Tomogrpah Imaging of
Alpha Orionis, Cycle 4 High)
The Faint Object Camera (f/96) was used to make ultraviolet
observations of the super giant star Alpha Orionis (aka, HD39801,
Betelgeuse). The observations were executed as scheduled, and no anomalies
were noted.
1.9 Completed WF/PC-2 5371 (HST Medium Deep Survey: Cycle 4 Medium Low
Galactic Latitude)
The WF/PC-2 was used in parallel with the prime science observations
to make low galactic latitude deep multicolor images of objects such as
galaxies, and stars in our galaxy. The observations were completed as
planned, and no problems were reported.
